Set the Transaction Date of a Purchase Order that Contains Drop Ship Items to its Sales Order Source Approval Date

When a sales order with drop ship items is approved, a purchase order is automatically created by the system for the purchase orders.  However, the system automatically sets the transaction date for the newly-created purchase order to the date when the sales order was created, not when it is approved.

For most business use cases, the transaction date of a purchase order must be set to when it was created, which in this case, is the date when the originating sales order was approved.  A good way to achieve this behavior is to create a worfklow with the following settings:
